    The paper describes how the Design Structure Method (DSM) can be used to analyze the information flow inherent in requirements to re-engineer the design process. DSM is used to develop a design plan showing how to organize design teams, the communication within and between teams, the order in which tasks can be done and which can be done simultaneously, where to use estimates, how design iteration is to occur, and where design reviews are needed and what to review. It is useful in coordinating collaborative design effort by showing who gets what information and when. It is valuable in planning for concurrent engineering by allowing one to go back to the requirements rather than being constrained by the task structure of the old process. While the focus is on the product development process, the author is also looking at using these techniques to re-engineer business systems View full abstract»

    The engineering data of a large enterprise is typically distributed over a wide area and archived in a variety of databases and file systems. Access to such information is crucial to a team member, particularly in a concurrent engineering setting. However, this is not easy, because (1) a model of the relevant information is not available, and (2) there is no simple way to access the information without being knowledgeable about various computer data formats, file systems, and networks. The authors have developed a system called the Information Sharing System (ISS) to enable access to diverse and distributed information within a corporation. Such data could be stored in different repositories such as databases and file systems including those that contain multiple media. The paper describes the methodology fo the ISS, the details of the implementation nd extensions planned for the future View full abstract»

    The barriers to concurrent engineering (CE) are cultural, organizational, and technological in nature. A successful implementation of CE requires that these barriers be identified up-front. The Concurrent Engineering Research Center (CERC) has developed a model, a measurement tool, and a methodology-the Readiness Assessment for Concurrent Engineering (RACE)-to assist CE implementors in identifying the barriers and prioritizing implementation actions. The authors discuss the readiness model, the process, and the questionnaire associated with RACE. They also identify some open issues concerned with conducting a readiness assessment and interpreting the results. Finally, the concept for a computer-based tool for readiness assessment is described View full abstract»

    The paper presents an interactive tool, classified as a multiuser worksheet. The worksheet is integrated in a more general environment to support design and project in the domain of mechanical engineering. The worksheet serves two purposes: it supports flexible interaction with engineering data produced and consumed by components of a project support environment (geometric modeling, structural analysis, reliability analysis, etc.); and it supports multiuser interaction, allowing group activity and concurrency in the mechanical engineering design process. The design and implementation of the worksheet follows the object oriented approach and assumes the support if a shared window system. the paper describes the worksheet's design and emphasizes the relations between the notions of hierarchy and public/private workspaces, as well as the control of the sharing and concurrency aspects of a multiuser interactive system View full abstract»

    COMIX (cooperative multiuser interface to X applications) is a tool to share single-user X applications among several workstations on a computer network. Sharing an X application means that different users can view the graphical interface and output of the application at the same time on their screens and can interact with the application according to some chalk-passing protocol. Single-user X applications are applications developed with no collaboration ideas in mind. Using application sharing tools such as COMIX, the non-collaborative applications that typically can be used only by a single user can now be used in a collaborative mode by several users. The model used for sharing applications, the architecture of COMIX, and some of COMIX's internal details are discussed View full abstract»

    Patient centred healthcare delivery is an inherently collaborative and information-intensive process. It involves a wide range of individuals and organizations with different roles. The key to cost reduction and quality improvement in health care is effective management of this collaborative process. The Concurrent Engineering Research Center (CERC) developed a number of key technologies to enable collaborative processes. These technologies, integrated into an open collaborative environment, is currently being customized to create a research testbed, ARTEMIS, that addresses all aspects of patient-care life-cycle. ARTEMIS will equip each provider with his own personal assistant-a customized role-oriented workstation connected to his own information world through an information bus. With ARTEMIS, the users will be able to process multimedia patient-care information: look-up, compute, communicate, archive and collaborate View full abstract»

    The paper describes a new project intended to provide a firmer theoretical and empirical foundation for such tasks as enterprise modeling, enterprise integration, and process re-engineering. The project includes: (1) collecting examples of how different organizations perform similar processes, and (2) representing these examples in an on-line `process handbook' which includes the relative advantages of the alternatives. The handbook is intended to help: (a) redesign existing organizational processes, (b) invent new organizational processes that take advantage of information technology, and perhaps (c) automatically generate software to support organizational processes. A key element of the work is a novel approach to representing processes at various levels of abstraction. This approach uses ideas from computer science about inheritance and from coordination theory about managing dependencies. Its primary advantage is that it allows users to explicity represent the similarities (and differences) among related processes and to easily find or generate sensible alternatives for how a given process could be performed View full abstract»

    Typically, applications are built only after the database schema is available. To enable the application designer/programmer with the tools necessary to forge ahead without having to wait for the data schema definition, a change from traditional methodologies must take place. The paper proposes an alternative design methodology intended to bring applications on-line as soon as possible. The author looks at using Martin's subject databases and ties it together with Inmon's paradigm for decision support systems used in a distributed data system View full abstract»

    The paper examines how negotiation in distributed artificial intelligence (DAI) acts as in integral component for the development of tools necessary to support collaborative enterprises. As an example of how negotiation plays a key part, the author examines its use for conflict resolution among participants involved in the concurrent design of connections in buildings. The Designer Fabricator Interpreter (DFI) System, a knowledge-based tool which fosters interaction among structural engineers (designers), fabricators and erectors is described. The system's architecture models the participants as semi-autonomous computer agents which reason from their design evaluation perspectives. Alternatives are proposed through a novel incremental negotiation method called knowledge-based negotiation. The resulting negotiation methodology provides for potentially `better' designs as a result of differing agent viewpoints View full abstract»

    To be effective in practice, concurrent engineering requires access to and organization of knowledge accumulated over time, product versions, and customers. More important, separate knowledge resources have to be shared and coordinated over space and time if successful design is to be accomplished. The authors, address the nature of communication in design, especially across disciplines, and the support systems that facilitate better communication. While a lot of research effort is being expended on same-time communications within a group, they consider, as well, the need for, and the problems associated with, different-time, different-placed communication. they present these views in connection with an on-going development effort, n-dim View full abstract»

    One method of speeding up traditional engineering activities is by introducing parallel development paths. Although cycle time is reduced, coordination and project documentation become more difficult and are further exacerbated by synchronous collaboration. These needs can be addressed by capturing, accessing, and reusing knowledge consisting of the design, together with its rationale and development history. Successful capturing of design knowledge includes these elements and answers to several questions: What is the design? How was the design achieved? Why were choices made? The paper describes how to capture the history of the informal phase of the specification and design process using the Collaborative Environment for Concurrent Engineering Design (CECED) View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (580 KB)  

    A fundamental issue in developing collaborative engineering systems is the representation and management of the design rationale. A system for capturing the design rationale needs to represent and manage the intent evolution, the artifact evolution, the relationship between intents and between intent and artifact, as well as the different inputs from different designers. The authors describe an information system, SHARED-DRIMS, which was developed for encoding design rationale in DICE, a distributed and integrated environment for computer-aided engineering. SHARED-DRIMS consists of satellite modules attached to each agent, and a central core connected to all the professionals involved. Each module has three parts? (1) a comprehensive knowledge base, (2) a product model, and (3) a design intent-recommendation model (DRIM). In addition, the framework contains mechanisms for checking interactions and presenting hypotheses about the reasons for the interactions View full abstract»

    Complex distributed office procedures are based on sequential and parallel execution of basic services offered by a distributed server environment. Office procedure execution can be considered to be a special kind of group communication with groups of collaborating servers. The paper first presents a general group communication abstraction. The author then shows in detail how the generic approach has been extended and specialized in order to support complex office procedures. The extended solution comprises a graph-based, declarative specification notation for office procedures, and a distributed runtime support environment. This maps office procedure service requests dynamically to actual servers for execution. Moreover, additional management facilities enable external supervision of office procedures. Based on examples, he shows how applications can benefit from the abstractions. By discussing their similarities and evolution, he also outlines the strong relationship between group communication and office procedures View full abstract»

    The paper is a summary of experience in applying the concurrent engineering (CE) enabling technology concepts of the Concurrent Engineering Research Center (CERC) to existing business processes and architectures as a member of an IBM Federal Systems Company (FSC) Quality Improvement Team (QIT). As follow-on to this effort, a role for profiles such as the Government's Open System Environment (OSE) Profile, the National Institute for Standards and Technology (NIST) Application Portability Profile (APP), is proposed as the basis for a CE profile for integrated tool and information development architecture in support of CE. Use of a profile is stressed as a foundation for transition to an automated and integrated CE infrastructure in any enterprise View full abstract»

    As manufacturing enterprises form partnerships with both local and international partners, there is an increased need for a public collaborative framework for communication of information, cooperation among team members, and coordination of project tasks. The paper describes how Singapore's National Information Infrastructure (NII) can be used to rapidly build such a public collaborative framework for manufacturing enterprises. This framework will allow these companies to integrate their internal operations, collaborate with other companies, and access information for strategic business planning as well as product design. The NII will provide transparent computing services and large-grain reusable objects. Software development will be transformed from custom-made applications to a component-oriented industry. With the NII, the proposed public collaborative framework will have a nation-wide testbed on which it can be implemented and evaluated View full abstract»

    The SHARE project seeks to apply information technologies in helping design teams gather, organize, reaccess, and communicate both informal and formal design information to establish a `shared understanding' of the design and design process. The paper presents the visions of SHARE, along with the research and strategies undertaken to build an infrastructure toward its realization. A preliminary prototype environment is being used by designers working on a variety of industry sponsored design projects. This testbed continues to inform and guide the development of NoteMail, MovieMail, and Xshare, as well other components of the next generation SHARE environment that will help distributed design teams work together more effectively View full abstract»

    In a cooperative design environment many users need to be aware of modifications made to shared data. Traditional concurrency control mechanisms may cause data to be locked for long periods of time. A mechanism, which helps client programs to keep shared data up-to-date is presented. The mechanism is based on asynchronous notifications. In addition to ensuring consistency between different clients, the same model can be used to retain many consistent views (windows) to data cached on the client. The mechanism can be extended to support more complicated groupwork protocols View full abstract»
